Supply air unit with radiator

Background of the Invention

The invention relates to a supply air device 5 for improving ventilation of buildings in connection with a radiator, which device is connected to a supply air duct arrangement and is intended to direct the supply air through the radiator into a room, the device comprising a box structure extending below

In order to ensure trouble-free ventilation of buildings, and in particular mechanical ventilation systems, supply air intake, that is to say, no cold draft, even in cold seasons, has proven that incoming supply air must be heated.

The necessary heating is done by means of a radiator, In order to do this, the supply air must be led to the radiator. In both new buildings and renovations, it is often the most economical way to supply the supply air through a radiator located under the window, utilizing wall-mounted ducts.

Such a method of heating the supply air is known in the art. Problems with old so-called. In fresh air radiator systems, it has been radiators have been special; 20 special products built for this purpose, which, due to the possible filter change and cleanability, are reversible and thus their construction and small production volumes ;; therefore relatively expensive or to avoid opening the battery

* I

'·' Air arrangement, so-called The supply air box is only suitable for radiators that are not · · equipped with safety grilles, ie special radiators must be used; 25 again. Another difficulty is that old fixed supply air box / radiator systems are also difficult to clean.

; : Devices of the type described below, which are directly applicable to the conventional radiators with current grille, have been developed. Significant economic benefits can be achieved by using standard batteries compared to special batteries with a fixed supply device normally located at the back of the battery. In this case, the structure also has a ducting structure by which the supply air can be introduced from the supply air duct located under the window frame. This property is for building. often a desirable feature.

,: 35 However, there are problems with these solutions with regard to the placement and design of the supply air filter.

Brief Description of the Invention

An object of the invention is to eliminate the problems associated with the supply air filters of current supply air devices. This is achieved by the supply air device according to the invention, characterized in that the supply air filter condenses at least 5 on one side to the surface of the radiator at the bottom of the radiator.

This solution is simple, reliable and inexpensive because conventional filter structures can be utilized.

In the supply air device according to the invention, the supply air box with air filters is also independent of the structural height of the radiator. There will be 10 actions with one battery type specific supply air box.

It is also characteristic of the invention that all duct surfaces can be cleaned with, for example, a vacuum cleaner or a radiator brush, and that the air filter is easy to clean or replace.

Because the radiator does not need to be opened, there is no need for Sara-15 witch valve and bracket systems, which improves system reliability, reduces maintenance and reduces costs.

By appropriately dimensioning the supply air device, standard brackets can be used to attach the battery.

BRIEF DESCRIPTION OF THE DRAWINGS In the following, the invention will be explained in more detail in two different embodiments. with reference to the accompanying drawings, in which, '' *, Figure 1 illustrates a first embodiment of a single-plate

in connection with ^ as a principle view from the side; '; Fig. 2 illustrates a first embodiment of a two-plate thermal cushion: 25 in plan view from the side; Figure 3 illustrates another embodiment of a single-plate radiator in plan view from the side; and Figure 4 illustrates another embodiment of a two-plate radiator as a plan view from the side.

DETAILED DESCRIPTION OF THE INVENTION: Figures 1 and 3 show a single plate radiator 1 having: a radiator plate 1a, a convection damper 1b and a protective grille 1c. 2 and 4: the radiator T differs from the radiator 1 shown in Figs. 1 and 3 only in that there are two radiator plates 1a and convection plates 1b. Of course, the invention can be applied to a radiator of even more width.

In each of the solutions shown in the figures, a longitudinal supply air box 2 is connected to the lower part of the radiator 1,1 ', within which the lower part or side of the box 2 can be opened for changing the filter 3 or cleaning the structure.

5 The filter 3 is sealed between the radiator plates 1a 'in the double plate radiator models 1' and ends at the supply air box 2. In the single plate models 1, the filter 3

In the first embodiment shown in Figs. 1 and 2, the funnel outlet 6 is located, for example, under a window frame and the air in the flat duct 4 is led down to the supply air box 2. The length of the flat duct 4 For example, the wall outlet 6 may be flat square or circular. The flat duct 4 is closed at least from the top and the sides to the mounting surface of the radiator, i.e. against the wall 10 and the radiator 1,1 ', and from the al-15 to the supply air box 2. For the same duct structure 4 to suit all types of batteries the facing surface may be open, i.e., it also has a wall facing the side of the radiator and closely connected to the side walls and the cover. At the top of the duct structure 4 is an openable cleaning lid 5 which allows the duct structure 4 and the wall outlet 6 to be cleaned.

In the embodiments shown in Figures 3 and 4, the wall lead-through 6 'is supported. lee directly to the supply air box 2, where only the supply air box is needed! L (2 upper surface sealing plate 9.

For double- and multi-plate radiators, radiator 1 'is required; 25 side guides 11 at the ends to guide the air upwards. In single-plate models, similar air control is achieved by the space delimited by the convection damper 10 and the flat: wall channel 4, alternatively a sealing element (not shown):. Alternatively, the guide plate 8 may also be used.

In the supply air box 2, the air is distributed over the entire length of the box and flows through the air filter 3 to the heating surfaces of the coil 1,1 'and thereby to the room.

The foregoing description of the invention is merely intended to illustrate the basic idea of the invention. However, one skilled in the art can: implement its details in several alternative ways within the scope of the appended claims.
